ABSTRACT:
A structure includes a semiconductor substrate having semiconductor devices formed on or in the substrate. An interconnecting metallization structure is formed over and connected to the devices. The interconnecting metallization structure including at least one dielectric layer. A passivation layer is deposited over the interconnecting metallization structure and the dielectric layer. At least one metal contact pad and at least one dummy metal structure are provided in the passivation layer. The contact pad is conductively coupled to at least one of the devices. The dummy metal structure is spaced apart from the contact pad and unconnected to the contact pad and the devices.
